Since we talk mostly about the "entertainment" pieces of software, the answer is that there is either code, data (like tables for effects and co.) sound stuff, gfx stuff. While VIC is not used there due to limitations in every second VIC bank, that leaves us with code, data, sound stuff.

It is certainly not "obvious" but it is quite "typical" because the players are ready, the sound data is ready, the interface to the player is ready. And it contains "useful stuff" like code (for the player) and SID data. Making it relocatable would require noticeable effort and caution in order to not run into troubles. So - no, it is not "obvious", not "optimal", and not even "very good" way but rather a "least effort compromise".

OK - no more ;-)

Sure! Undoubtedly. :-)
